Hybrid tea rose plant named ‘KORmixosia’

ABSTRACT

A new and distinct variety of rose with long lasting, novel pink flowers, and attractive foliage with good disease resistance. It exhibits uniform upright growth with abundant flowers. The new variety propagates well by grafting. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

CROSS REFERENCES AND FEDERAL R&D STATEMENT

There are no cross referenced or related applications. This variety was developed without the aid of any research grant.

Latin name of genus and species: The botanical classification of the new rose plant is Rosa hybrida.

Variety denomination: The denomination of the new variety is ‘KORmixosia’.

BACKGROUND OF THE INVENTION

The new variety of rose plant of the present invention originated from a controlled crossing in a breeding program of two distinct parents during the summer of 1999. The parents utilized in the hybridization were ‘Osiana’, a patented rose with U.S. Plant Pat. No. 7,660 filed on May 31, 1990; and an un-named seedling created by the same inventor.

The resulting seeds were planted during the following winter. The resulting seedlings were evaluated and exhibited distinctive physical and biological characteristics. The new rose plant was selected as a single plant from the seedling beds due to its superior characteristics and asexually propagated for further evaluation. This new and distinctive rose variety is named ‘KORmixosia’.

SUMMARY OF THE INVENTION

The new rose plant may be distinguished from its seed parent, ‘Osiana’, by the following combination of characteristics:

-   -   1. ‘KORmixosia’ has cream-apricot blooms with a long, high         centered bud while ‘Osiana’ has champagne colored blooms with a         rounded bud; and     -   2. ‘KORmixosia’ has flowers with moderate fragrance while         ‘Osiana’ has little to no fragrance.

The new rose plant may be distinguished from its pollen parent, an un-named seedling, by the following combination of characteristics:

-   -   1. ‘KORmixosia’ has cream-apricot, very double flowers while the         un-named seedling has dark pink, double flowers; and     -   2. ‘KORmixosia’ has flowers with moderate fragrance while the         un-named seedling has a strong fragrance.

The objective of the hybridization was to create a new and distinct rose plant with unique qualities, such as:

-   -   1. Uniform growth and flowering;     -   2. Abundant attractive, recurrent, and fragrant flowers;     -   3. Attractive and abundant foliage; and     -   3. Resistance to diseases encountered in landscapes and gardens.

This combination of qualities is not present in prior rose cultivars. These objectives have been substantially achieved and in that distinguish ‘KORmixosia’ from all other varieties of which we are aware.

As part of a rose development program, Tim-Hermann Kordes germinated seeds from the aforementioned hybridization and conducted evaluations and observations on the resulting seedlings in a controlled environment in Offenseth-Sparrieshoop, Germany. The resulting seedlings exhibited distinctive physical and biological characteristics. The new rose plant ‘KORmixosia’ was selected in May, 2000 from the seedling beds to be asexually propagated for further evaluation. The first asexual propagation of ‘KORmixosia’ was done by budding to seedling understocks in July, 2000 at the W. Kordes Söhne Nursery in Offenseth-Sparrieshoop, Germany.

This initial and other subsequent propagations conducted in controlled environments show that the foregoing and all other characteristics of ‘KORmixosia’ come true to form and are transmitted through succeeding generations.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color illustration shows as true as is reasonably possible to obtain in color photographs of this type, the typical characteristics of the foliage, flower buds, and flowers of ‘KORmixosia’.
